Bath, 1761. Lizzie Yeo has had a hard life, but fortunately secures a position as wet nurse for the young son of vicar Jonathan Harding. When the boy starts school, Harding finds her a job with local apothecary Mr. Leslie, delivering the curing waters of Bath to invalids. But when a body shows up in the river, and her friend Nancy disappears, Lizzie is determined to find answers. However, she is being watched, and after she is attacked in the street and then caught in a deadly house fire, it’s clear that someone wants her gone. But who? And is it all connected to The Woman in the Water?
